    Default 30 hp rpc questions

    I have built a 10 hp finch Williams model some time ago and have been very pleased so far .

    As luck would have it , I have purchased some new to me machines that will be too much for my rpc to support .

    My question(s) is :
    - if the fw design is for a 10 hp motor and I'm looking to build a 30 hp unit is it just as simple as multiplying all components sizes by 3 ?

    40 amp starter would be 120 amp

    30 amp starter would be 90 amp

    1500 micro farads of start capacitance would be 4500 micro farads ?

    Thanks fellas
